2025R Mystery

[CobyRupert]

Don’t take this wrong, but many people don’t know that when extra torque is needed to pull a load or climb a hill, you lift up on the hydrostatic pedal. That’s the equivalent of shifting to a lower gear. Yes, like a lower gear, pressing less results in more torque, less speed. Lifting up on the pedal is a bit counterintuitive, it’s is not like a gas pedal in a vehicle that you mash down when more power is needed.

If not that, then it sounds like you’re not getting enough fuel, or possible air. If not enough air, I think you’d notice black smoke. Not enough fuel could be a list of things. Starting at the tank, make sure there’s no objects that obstruct the lift pump’s intake and go downstream from there.

No offense taken. Yeah, the problem is that to spray effectively, I need a constant speed and when I let up on the drive pedal, I lose speed. I’ve tried this, but then I’m just going way too slow and overspraying. Before I try accommodating for a slower speed (which means I need to go that same speed downhill), I’d like to try and figure out what changed with the tractor. Ultimately, I could just circle around and go down each row, but again I’d rather try and figure things out. Looks like I need to figure out how to look in the tank and at whatever screen is in there.

I’ll throw another idea out, maybe it’s normal. How steep is athe hill and how much power does your sprayer take? I have a fairly steep hill I mow. When going up the hill I can’t put the hst pedal down all the way or it will stall out. With the mower off it won’t bog down on the same hill.

It’s between 20 and 25 degrees. But the issue is that the thing worked fine for the past three years…. and now it struggles. There’s no doubt it’s operating at the top of it’s range, but I had to do that because my rows are 6 feet wide- and the vines take about another 6 inches on either side when they’re grown out so a 3 series is just too wide.

What I gather from this problem is that this model tractor with HST is not what you need to spray. Either a higher horsepower tractor with HST and/or a gear tractor to maintain ground speed.
Sounds like the 2025R is not the answer to your need, sorry to say.

But it worked for three years...

If it used to pull the hill and no it won’t something is wrong. I still think it’s a fuel issue but lots of things it could be.

I agree - it did the same job previously, and now it doesn't - something is broken. Before I read your post about it working fine for three years, I was going to suggest adding a turbo, but since it did the job without it that's not the right solution.

Not saying you shouldn't add one after the problem is solved, but at this point it would be a bandaid

It still sounds to me like a fueling issue, and not air or hydraulics. I think your next step needs to be to recreate the problem, let it stall out, and jump off the tractor and start taking pictures in the position it stalled, then compare to a flat level surface. Could be something shifting slightly and pinching a line, could be a float not floating correctly or a pickup not picking-up.

Another test to try:

1. When it stalls, try to start it right away. Does it restart at idle?
2. If it doesn't restart, let it sit a minute, then try to restart. Does it restart?
3. If not, try cycling the ignition a couple times (without starting), then try to start. Does it start?
4. If not, roll back down to flat land, wait a minute, then try to start.

Im not sure if I misread something. But you noted it had water in the fuel but all that was fixed. Is there a chance that it's a problem with the HST and not the engine. How does it run? Idles ok. Revs up ok? Does the engine bog down, chig, or smoke? Or does it lack 'power' because it won't move due to transmission issue?
